Size and compatibility Double sided build plate mat measures 257.5 x 257.5 mm Compatible with Bambu Lab X1, X1Carbon, P1P, and P1S FDM 3D printers Also suitable for PLA, TPU, PETG, ABS and other filaments Please confirm your 3D printer platform size before ordering Double sided design for broader use and longer life Two usable faces: a rough textured PEI surface for strong adhesion and a smooth PEO surface for different materials Double sided design offers wider material compatibility and roughly twice the service life of a singlesided plate Gradient PEO sheet displays color variations when viewed from different angles, adding visual interest during printing adhesion without tape or glue Print directly on the frosted textured PEI surface or the smooth PEO surface adhesion at a heated bed around 60 C No glue or tools required to keep models in place on either side Easy print removal and reliable stability PEI provides stability while the spring steel sheet delivers flexibility and flatness The textured PEI surface combined with the spring steel ensures easy removals Prints release easily as the bed cools to room temperature; if needed, gently bend the build plate to release the model No scratching, prying, or damage to the print needed Practical use scenarios Printing multimaterial projects on a Bambu Lab X1 series printer, using PEI side for PLA or PETG and switching to PEO side for smoother surfaces Prototyping or functional tests with ABS at a higher bed temperature for reliable adhesion without tape Colorful or gradientready prints that benefit from the PEO face's reflective gradient to assist alignment and provide a visual cue during setup
